Control Effects of Florasulam·Halauxifen-methyl 20% WDG on Resistant Broad-leaved Weeds in Wheat Fields and Safety Evaluation

研究20%双氟·氟氯酯WDG对小麦田抗性阔叶杂草的防除效果及其对小麦的安全性。结果表明,20%双氟·氟氯酯WDG 75 g/hm^2对江苏沿海小麦田抗性阔叶杂草具有良好的防除效果,与20%氯氟吡氧乙酸EC 600 mL/hm^2混用,可提高对猪殃殃(Galium aparine)等抗性阔叶杂草的防除效果,对小麦生长安全。

The control effects of halauxifen-methyl 20%WDG on resistant broad-leaved weeds in wheat fields and its safety to wheat were studied.The results showed that florasulam·halauxifen 20%WDG 75 g/hm^2 had a good control effect on resistant broad-leaved weeds in coastal wheat fields in Jiangsu province.It was mixed with fluroxypyr 20%EC 600 mL/hm^2,which could improve the control effect of resistant broad-leaved weeds such as Galium aparine,and it was safe for wheat growth.
